TIRE STRUCTURE.

TQaZZwwmt/may concern.'

Be it known that I, ANDREW D. RozEBooM, a citizen of the United States, residin at Bowman, in thecounty of Bowman and tate of-North Dakota, have invented certain new and useful Improvementsin Tire Structures, of which the following is a specilicatron, reference being had to the accompanying drawings. Y

This invention relates to certain improvements in tire structures, and it is an object of the invention to provide a structure of this general character embodying novel and improved means wherebythe use of air is eliminated and wherein the structure possesses substantially the same degree of resiliency as a pneumatic tire. It is also an object of the invention to provide a novel and improved tire structure embodying a rim and a carcass connected one to the other and wherein the carcass proper comprises a construction possessing a certain degree of resiliency and wherein cushioning agency is interposed between the tread portion of the carcass and the rim.

The inventionconsists in the details of construction and in the combination andarrangement ofthe several parts of my Vimproved tire structure whereby certain important advantages are attained and the device lrendered simpler, less expensive and 'otherwise-more convenient and advantageous lfor use, as will be hereinafter more Vfully set fort-,hl Y

The novel features of invention will hereinafter be definitely claimed.

In order that my invention -may be the better understood, l1 will now proceed to describe the same with reference to the accompanying drawings, wherein:

-Figure l is a transverse sectional view taken through a tire structure arranged in accordance with an embodiment of my invention;

Fig. v2 is fa fragmentary view partly inside elevation and partly in section Iof the structure as herein disclosed;

Fig. 3 isa view in perspective of one of the bands embodied in my improved structure; and Y Fig.- 4 is a view in ,perspective `of a second type of band embodied in any improved structure.

As disclosed in )the accompanying drawings, R denotes 1a rim adapted to be mounted upon the felly of a wheel in any ordinary or Specification of Letters Patent.

preferred manner and said rim is provided at substantially its transverse center with the inwardly disposed and continuous bead or rib l, having its opposite side faces lprovided with the continuous recesses or channels 2. vSaid rim, at predetermined points spaced circumferentially thereof, is provided therethrough with the threaded openings 3 which also extend through the rib or bead 1.

C denotes the carcass comprised in my improved structure `and said carcass, as herein disclosed, comprises series of circumferentially related super-imposed'metallic bands Ltof relatively narrow width and curved longitudinally in accordance with the conventional cross sectional configuration of a tire. In the present embodiment of my invention, the bands L of each series are five in number, althoughl do not wish to be understood as limiting myself in this respect as said bands may be of any number but preferably `from five tornine dependent upon the load adapted to be imposed upon the structure. The bands 4 of adjacent series are in overlapping relation in order to preclude the passage of dirt or other foreign matter therebetween. In view ofthis overlapping relation of the bands 4 of adjacent series, alternate bands of each series at substantially the center thereof are provided with the openings 5 while the marginal portions of the interposed laminations are provided in their side edges with the notches or recesses `6, affording openings coinciding with the openings 5 ineach series. Disposed through f said openings of each series is a headed shank 7 having its head 7a overlying the outermost band, :and said shank is also disposed through registering openings 8 provided in circumferentially disposed and superimposedannulalr members 9, possessing a certain degree of inherent resiliency. The inner end ,portion of the shank 7 is threaded with* ing a -hollow or tubular Iboss l() lcarried by the innermost annular vmember 9. By this means, each series of bands 4 has its tread portion :effectively held in applied position. The annular members 9 in succession are of increased width with the narrower member disposed outermost. This is done in order that -said superimposed` annular members will offer no undue obstruction or hindrance to the ser-ies of bands-4.

Riveted, as at l1, to the 'outermost band 4 of each of said series is a lamination 1.2 of

fio

izo

Aor'outwardly` curved, as l at 17, to provide c beads-which snugly fit "withintlie 'annular Y grooves or' channels 2 vinthe side iacesof leather or other suitable material, said lamination being of substantiallythe same width.

as the'outermost banda-nd extendingentirely tlicrealong.

Y I also find it of advantage to have the an- Vnularmembers 9 between adyacent Shanks provided withthetransversely disposed corrugations 14: and which corrugations permit Y a certain degree of expansion or contraction of the annular memberl9 in a 'circumi'erentialdirection and whereby the requisite resiliency ofthe carcass is vmaterially facilitated.

vJlhreaded within the outer end portion of 'each ofthe openings 3 is a plug or member 15y provided at its 'aXial centerV with an in`r ivardly disposed linger' or arm "16. Seated within theinne'r end portion of each `ofthe openings 3 is. an end portion of an expansiblefmember E, herein d .isclosedas a coil spring, and which inserted end portion surrounds the nger4 or rarm YVThe opposite end 'portion ofvv the eXpansible member or spring surrounds the boss l0 whereby said boss serves as a retaining' means Jfor said outer end portion of the member E. By ad'- justing the plugfor member 15 longitudinally ofthe opening 3, the 'tension of the eXpansible member or spring E may be regulated yor varied'as maybe requiredin practice.

Each of the membersor springs-E serves as a cushioning agency coacting with each series of imposed bands aand Avwhereby the eiliciency of the tire is materially vfacilitated. f The end portionsof the bands 4 are flexed the rib or bead l] Saidv beads 17 are-hel'd fin applied vposition Vwithin "the groovesA or channels '2 through theV instrumentalityoi the 'removablel ringslS' locked tof'therim the removable screws 19, or the likei v From'- hC foregoing v`description, it -is Vthought to'be obvious that a tire lstructure constructed Vin accordance with my inven- Ytion isjparticularly well adapted for use by reason of the conyen'ienceand facility withV 'which it may be assembled and, operated, and

it will'alsobe obvious that myinvent'ion is susceptible of some change and modification without departing fromthe principles and spirit thereof, and fort-his reason, 'I' do not "wish tol be understood as limitingmyself'to vtheprecise 'arrangemeiit and formation'of tliegsever'alf parts'herein Ashown in carrying out my, invention in'A practice except as hereinafter claimed.
